FIPK guys check your hex head bolts!

[Romans8:28]

For the third, and hopefully last time (thanks lock-tight) I had to re-tighten the 4 hex head bolts that connect the filter/cone to the MAFS housing/body. Especially the one on the bottom closest to the front tire (it was backed out a 1/4" !)

If your idle becomes erratic and or your car's performance all of a sudden is down (in say a good 3/4 gear pull) and you run a FIPK, be sure and check the mounting hardware!

This has happened to me at least three times now..... I don't see why these bolts back out for, unless there is far more vibration at speed than it would seem

Thanks for info

did you omit the lock washers or something?

No they have always been there, thats what blows my mind!

I really don't see why these bolts/screws back out over time, being they are hex head (as opposed to say phillips) you can tighten them good. I alternated back and forth as I tigthened them down, but yet they still loosen after a couple months.

If the lock-tight does not work, I guess I will just plan on a monthly re-torque
